INSTALLATION INSTRUCTIONS
(CONT.)
Electrical (cont.)
Voltage
Voltage at motor
MUST NOT
be more than 10% above or below motor name plate
rated voltage, or motor may overheat, causing overload tripping and reduced
component life. If voltage is less than 90% or more than 110% of rated voltage when
motor is running at full load, consult power company.
Grounding/Bonding
Install, ground, bond, and wire motor according to local or national electrical code
requirements.
Permanently ground motor. Use green ground terminal provided under motor canopy
or access place; use size and type wire required by code. Connect motor ground
terminal to electrical service ground.
Bond motor to pool structure. Use a solid copper conductor, size 8 or larger. Run wire
from external bonding lug to reinforcing rod or mesh. Connect a No.8 AWG (8.4
mm
2
) solid copper bonding wire to the pressure wire connector provided on the motor
housing and to all metal parts of swimming pool, spa, or hot tub, and to all electrical
equipment, metal piping or conduit within 5 ft. (1.5 m) of inside walls of swimming
pool, spa, or hot tub.
Wiring
If other lights or appliances are also on the same circuit, be sure to add their amp
loads before figuring wire and circuit breaker sizes.
(NOTE: If unsure how to do this
or if this is confusing, consult a licensed electrician)
. Use the load circuit breaker as
the Master On-Off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-circuit
to ground and disconnect power before it becomes dangerous to pool users. For size
of GFCI required and test procedures for GFCI, see manufacturer’s instructions.
In case of a power outage, check GFCI for tripping, which will prevent normal pump
operation. Reset if necessary.
NOTE: If you do not use conduit when wiring motor, be sure to seal wire opening
on end of motor to prevent dirt, bugs, etc., from entering.
